Mistress Dana was out to do some crazy things to this guy because of how pissed she was at him. That is why she chose to use her pony play to dominate him but that was not all as she also used her ass to dominate him. The mistress had him lick and smell her ass and he had never had to do such a thing so it was humiliating.
These mistresses wanted to distract and dominate this guy so they did it and they did it with their facesitting fetish. The mistresses were of the opinion that they needed to crush as well as humiliate the guy and they did it with their hot asses after they had turned him into a human pony. He was shocked and pained but there was little he could do about it. He learned his lesson.
These mistresses wanted to train their slaves on what to do and how to do it when it came to pony play. The mistresses have a fetish for pony play and they wanted to make sure that their slaves were competent enough to do all that the mistresses wanted. So they taught them how to be pros at it and ensured that they were ready to be human ponies in a couple of days.
Mistress Claudia was done with her last human pony and she now had a new one. She was excited about trying it out and she did not go easy on it at all. She had to make sure that she had the fun she had been looking forward to having. So she rode the new human pony and she whipped it when it did not do things the way she wanted.
Madame Marissa had run out of options to punish her slave. She wanted to find a new way to do it so she went on the internet and she searched for what she could do and enjoy it even as she punished him. She settled on pony play so she turned him into a human pony. She enjoyed getting him to ride her for hours until he was not able to do it anymore.
Madame Marissa can stomach a lot of things from a slave but she cannot stomach a slave being rude to her. She kicked the slave hard and threw him on the couch when he was rude to her. It was the first and last time he was ever rude to her. The punishment he received plus being rode like a pony taught him a lesson he has never forgotten to date.
